Abstract

Ces pinces comportent deux mors 1a, 1b de serrage de la tôle 3, agissant sous l'effort du corps de révolution 5 exercé par ses surfaces 6a, 6b, tendant à écarter les extrémités de mors opposées aux surfaces de prise 2a, 2b, qui sont maintenues par deux boulons 4 symétriques. Le serrage est d'autant plus energique que l'effort de traction exerce par une machine tel un vérin hydraulique sur l'étrier 10 est plus élevé. Le dispositif est destiné au dressage de tôles de véhicules accidentés.These grippers comprise two jaws 1a, 1b for clamping the sheet 3, acting under the force of the body of revolution 5 exerted by its surfaces 6a, 6b, tending to separate the ends of the jaws opposite the gripping surfaces 2a, 2b, which are held by two symmetrical 4 bolts. The tightening is all the more energetic the higher the tensile force exerted by a machine such as a hydraulic cylinder on the caliper 10. The device is intended for straightening sheet metal from damaged vehicles.
